You’ve seen the effect before in movies and television – someone is talking in the background, then as their conversation finishes, the scene quickly transitions to the foreground, and all the cameraman did was adjust the camera’s lens focus. It’s a quick and almost seamless transition, and you can achieve the same effect too, using just your DSLR camera.

Using an inexpensive kit called Follow Focus, you can now adjust your shots with professional perfection. The kit, which is sold for $59, is easy to use and replicates the same photograph technique it’s named after, follow focus.

The kit includes a Velcro strap and metal focus markers that are actually used as stop points to set the proper focus. Having the two points allows you to switch back and forth between the multiple focus points with the accuracy and precision of a professional photographer or filmmaker. If you don’t want to spend the $59 dollars, you can build a kit without much difficulty, using metal clips, velcro and steel wiring, but we thought the Follow Focus kit was well worth the money considering the professional results you get.

Created by DSLR Solutions, the Follow Focus kit allows follow and rack focusing without a rail or other accessories.
